Around 1600, a circle of intellectuals produced in Firenze an experimental genre: the Dramma per musica. Starting from these premises, the until then composer of madrigals and sacred music Claudio Monteverdi, created in 1607 a work with an assortment of possibilities unheard of until then: a combination of dances, choirs, dialogues and solos, incrementing of the orchestral color, enormous enrichment of the vocal line. With this, the "reciting singing" of the beginning of the century opened to a dramatized song of infinite resonances in the history of opera.
